Ok, we have progress, now get the following error but I think this is due to not having the msp430 dev board connected since I’m at home.

Does this look ok to you? I’ll test with the dev board when I’m back in the office. Looking promising, thanks so much for your fast responce

As the message says I have tried re-running with pio run -t upload --allow-fw-update however, as a suspected --allow-fw-update is not a Platformio command but rather a MSP debug command. I will try and install MSPdebug manually and perform and update…tbc

I am still running into this issue on ubuntu 17.04. If i do update the firmware on the FET it bricks the FET. The only way to rescue the FET is to take it to CCS on a windows machine and allow CCS to ‘rescue’ the device.

I also just tried to upload onto an msp430 launchpad, same processor just not using the stand alone FET. Exact same result, PIO barked at me about fw version of the FET. Tried to upload new fw to the FET annnnnd now its bricked.
